Your brother knew the risk. And anyone who buys the farm in such activity will inevitably be the butt of jokes, the Darwin Awards being the most notorious. This isn't like some innocent person driving down the road and getting T-boned by a drunk driver. For your brother, the risk, the chance of death was part of the adrenaline rush. And that came with a very high price in the end.
This is our pet necro-troll. Whenever we have a thread about some moron doing something stupid and getting killed, s/he/it shows up, claiming to be a close relative of the decedent, and berates us.
